Reading

渝粤教育

Read the following passages and choose the best answer for each of the following questions.

?　How man first learnt to invent words is unknown; in other words, the origin of language is a mystery. All we really know is that man, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to stand for those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words.

　　The power of words, then lies in their association which the things they bring up before our minds. Words became filled with meanings for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of words that mean something to us increases.

　　Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions. We should therefore learn to choose our words carefully and use them exactly, or they will make our speech silly and impolite.
